DESCRIPTION
Texture format support varies depending on driver, hardware, and usage flags. In general, you should use SDL_GPUTextureSupportsFormat to query if a format is supported before using it. However, there are a few guaranteed formats.

FIXME: Check universal support for 32-bit component formats FIXME: Check universal support for SIMULTANEOUS_READ_WRITE

For SAMPLER usage, the following formats are universally supported:

• R8G8B8A8_UNORM

• B8G8R8A8_UNORM

• R8_UNORM

• R8_SNORM

• R8G8_UNORM

• R8G8_SNORM

• R8G8B8A8_SNORM

• R16_FLOAT

• R16G16_FLOAT

• R16G16B16A16_FLOAT

• R32_FLOAT

• R32G32_FLOAT

• R32G32B32A32_FLOAT

• R11G11B10_UFLOAT

• R8G8B8A8_UNORM_SRGB

• B8G8R8A8_UNORM_SRGB

• D16_UNORM

For COLOR_TARGET usage, the following formats are universally supported:

• R8G8B8A8_UNORM

• B8G8R8A8_UNORM

• R8_UNORM

• R16_FLOAT

• R16G16_FLOAT

• R16G16B16A16_FLOAT

• R32_FLOAT

• R32G32_FLOAT

• R32G32B32A32_FLOAT

• R8_UINT

• R8G8_UINT

• R8G8B8A8_UINT

• R16_UINT

• R16G16_UINT

• R16G16B16A16_UINT

• R8_INT

• R8G8_INT

• R8G8B8A8_INT

• R16_INT

• R16G16_INT

• R16G16B16A16_INT

• R8G8B8A8_UNORM_SRGB

• B8G8R8A8_UNORM_SRGB

For STORAGE usages, the following formats are universally supported:

• R8G8B8A8_UNORM

• R8G8B8A8_SNORM

• R16G16B16A16_FLOAT

• R32_FLOAT

• R32G32_FLOAT

• R32G32B32A32_FLOAT

• R8G8B8A8_UINT

• R16G16B16A16_UINT

• R8G8B8A8_INT

• R16G16B16A16_INT

For DEPTH_STENCIL_TARGET usage, the following formats are universally supported:

• D16_UNORM

• Either (but not necessarily both!) D24_UNORM or D32_FLOAT

• Either (but not necessarily both!) D24_UNORM_S8_UINT or D32_FLOAT_S8_UINT

Unless D16_UNORM is sufficient for your purposes, always check which of D24/D32 is supported before creating a depth-stencil texture!

AVAILABILITY
This enum is available since SDL 3.2.0.
